Referring now to the figures, FIG. 1 illustrates an implementation of afrozen confection machine 100 that is configured to be portable. As canbe seen in the figure the machine 100 for conditioning ice may comprisea body portion having a housing 105 and a handle portion 110 forconvenient portability and positioning. The machine may further comprisea hopper 120 for receiving the ice to be conditioned. In animplementation the handle portion 110 may comprise a rubber material,grooves, a textured surface, and/or the like for providing grip formoving and holding the machine 100. The machine 100 may further comprisea lid 115 configured to cover the hopper 120. It will be appreciatedthat the lid 115 may comprise a transparent portion for monitoring icein the hopper portion. The lid 115 may further have a catch 125mechanism, such that when the catch 125 is released, the lid 115 isallowed to rotate or pivot upwards into an open position, such that icemay be introduced into the hopper 120 of the machine 100. In anembodiment, the lid 115 may be made of a clear material to provide theuser the ability to see the ice level in the hopper. Additionally, themachine may comprise a spout 130 and ice shaper 135 for delivering andshaping the conditioned ice into a cup or other container for receivingthe shaved ice product. It should be noted that the housing 105, lid115, spout 130 and shaper 135 may be made from any suitable materialsuch as for example: plastics and metals.

FIG. 2 illustrates a cutaway view of a frozen confection machine 200. Ascan be seen in the figure, a motor 202 may be disposed within thehousing 205 of the machine 200. The motor 202 may be electric and may bedriven by DC or AC current. An embodiment having a DC motor may bedriven by a battery that may also be disposed within the housing. Thehousing 205 may comprise a base portion 206 that is sized and shaped toprovide stability during use. The base portion 206 may comprise feet 207that provide traction and may be made from a vibration dampeningmaterial to reduce noise and vibration during use.

As also illustrated in the figure, the machine 200 may comprise a handleportion 210 that is configured to fit a user's hand for easyportability. The handle portion 210 may be aligned and configured so asto be held by a user during ice conditioning to compensate for forcesgenerated by the motor 202 and the paddle 212 while conditioning theice.

In an embodiment, the motor 202 may be directly connected to a driveshaft 242 that drives the paddle 212 thereby moving ice into a blade213. The blade 213 may be secured to the hopper 220, such that the bladeis stationary. It should be noted that in an embodiment the motor 202may drive a blade that spins in order to condition the ice. The motor202 may be disposed within the housing 205, such that the motor's axisof rotation is generally aligned with the body of the machine 200.Additionally, the axis of rotation of the paddle 212 may also begenerally aligned with the body of the machine 200. In an embodiment thehousing 205 may further comprise a door for easily accessing the bladefor maintenance.

An embodiment may comprise a motor that is indirectly connected topaddle wheel through a device with a transmission or gearing.

As can be seen in the figure, the machine may comprise a hopper 220 forreceiving and holding the unconditioned ice, and may comprise a spoutportion 230 for dispensing the conditioned ice after being processed andmoved throughout a portion the body of the machine 200. The spout 230may be configured to deliver conditioned ice into a shaper 235 forproviding a shaped top for the conditioned ice within a cup orcontainer. The shaper 235 may impart a shape to a final shaved iceproduct so that little or no additional shaping needs to be performed bya user. In an implementation, and additional flexible hand shaping flap233 may be included, which allows users more options for shaping duringuse without having to come into contact with the edible conditioned iceproduct. The flexible shaping flap may be attached below or near thespout as illustrated.

A lid 215 may be provided for covering the hopper 220. The lid 215 maycomprise a latch 217 for locking the lid 215 in a predeterminedposition. Additionally, the lid 215 may be configured so as to operate aswitch 240 that turns on the motor so that the machine may not beoperated without the lid 215 in place, or locked in place by the latch217. In one embodiment, the latch 217 or catch 125 may be omitted suchthat downward pressure provided by a user's hand and applied to the lid215 keeps the motor spinning and operational. This can be a safetyfeature so that when the downward pressure or force provided by theuser's hand is removed the motor and paddle 212 stop rotating and is notoperational. The lid 215 may be hinged 218 relative to the body of themachine 200 so that it rotates between opened and closed positions.

For example, during use the machine 200 may be positioned on a worksurface by a user by way of the handle 210. The user may then lift thelid 215 to expose the hopper 220, and ice may then be introduced intothe hopper 220. The lid 215 may then be closed and held down by thelatch 217, a user's hand, or other mechanism thereby actuating theswitch 240 to turn on the motor 202. The switch 240 may include a rockerswitch that provides an upward bias using a spring or other biasingmechanism, such that the lid 215 moves away from a closed or fullyclosed position when downward pressure is not applied and/or the latch217 is not secured. The motor 202 then turns the paddle 212 to drive iceinto the blade 213 (or drive the blade 213, in at least one embodiment).The ice is conditioned as it moves through the blade 213 and into thespout 230 and shaper 235. The conditioned ice may then be delivered to acup, or other container as may be desired by a user, and shaped by theshaper 235, and the flexible hand shaping flap 233, resulting in cup orcontainer full of conditioned ice or product, which may have apleasingly shaped top. For example, ice within the hopper 220 may be toolarge to pass through an opening or blade 213 covering an opening nearthe spout 230. Only after the ice is conditioned (chopped, shaved,turned into “snow,” or otherwise conditioned) is it able to pass from aninterior of the hopper 220 and out through the spout 230 into a cup.

In an implementation, an external switch may be provided for actuatingthe machine. For example the external switch may be a foot pedal orother switch for actuating the machine. After filling the cup withconditioned ice, a flavoring, drink, or other edible content may beadded to the conditioned ice for consumption.

FIG. 3 illustrates an exploded view of a frozen confection machine 300.The machine may be constructed primarily of two housing halves 305 a and305 b that may be joined together to thereby hold a motor 302, paddlewheel 312, and blade 322 in a working configuration relative to eachother. A paddle wheel 312 may include paddles located near a centeraxis, as in FIG. 2, or may include paddles located near a rim or edge,as in FIG. 3. As can be seen in the figure, the motor 302 may bedisposed within the housing 305 of the machine 300. The housing halves305 a and 305 b may comprise a base portion that is sized and shaped toprovide stability during use. The base portion may comprise feet 307that provide traction and may be made from a vibration dampeningmaterial to reduce noise and vibration during use.

As also illustrated in the figure, the machine 300 may comprise a handleportion that is configured to fit a user's hand for easy portability.The handle portion may be aligned and configured so as to be held by auser during ice conditioning to compensate for forces generated by themotor 302 and the paddle wheel 312 while conditioning the ice.

In an embodiment the motor 302 may be directly connected to a driveshaft 332 that drives the paddle wheel 312 thereby moving ice into ablade 322. It should be noted that in an embodiment the drive shaft 332may be connected to the paddle wheel 312 with a shaft connector 342. Themotor 302 may be disposed within the housing 305 a-b such that themotor's axis of rotation is generally aligned with the body of themachine 300. Additionally, the axis of rotation of the paddle wheel 312may also be generally aligned with the body of the machine 300. In anembodiment, the housing may further comprise a door for easily accessingthe blade for maintenance. For example, a door in the hopper or asidewall near the blade may be selectively opened to access remove,and/or replace the blade 322. In one embodiment, no door is needed toaccess the blade as it may be accessed by releasing one or morefasteners, such as screws, to allow a hopper portion 320 to be movedupward and access the blade from above.

As can be seen in the figure, the machine may comprise a hopper 320 forreceiving the unconditioned ice, and may comprise a spout portion 330for dispensing the conditioned ice after being processed and movedthroughout a portion of the body of the machine 300. The spout 330 maybe configured to deliver conditioned ice into a cup or container. Thespout may include a shaper 335 portion for providing a shaped top forthe conditioned ice within a cup or container.

The machine 300 may also include a lower wall 352 that encompasses alower portion of the hopper 320 or may form part of a wall of a hopper320. The wall 352 may include grooves for receiving and holding theblade 322 at an opening 360 in the lower wall 352. For example, theblade 322 may slide downward into the grooves to be positioned in frontof the opening 360 so that only ice that is conditioned is allowed toexit the hopper 320 through the spout 330.

A lid 315 may be provided for covering the hopper 320. The lid 315 maycomprise a latch for locking the lid in a predetermined position.Additionally, the lid 315 may be configured so as to operate a switch340 that turns on the motor so that the machine 300 may not be operatedwithout the lid 315 in place. Additionally, a power cord 350 may beprovided to power the machine 300. Various fasteners FF may be used tomount the various components of the machine together. Foot pads 344 maybe used to dampen vibrations created during use. Rubber grommets 346 maybe used to seal opening in the housing of the machine.

As can be seen in the figure, an embodiment may comprise drive shaft 332that is directly connected to and directly drives the paddle wheel 312.

FIG. 4 illustrates an embodiment illustrating the angle between a handleportion and the axis of rotation of the motor 412 and paddle 413 of amachine 400. Illustrated in the figure is a frozen confection machine400 having an angle 425 between a first line 420 drawn through thehandle portion 415 and generally aligned with the base portion of themachine and a second line 410 that represents the axis of rotation ofthe motor 412. The angle 425 formed by the intersection of the firstline 420 and the second line 410 may be chosen during design to dampenor otherwise negate forces generated by the motor 412 and the paddle 413as the machine processes ice. In an embodiment, the motor may bedisposed within the housing, such that the drive shaft of the motorrotates about an axis 410 that is fixed at an angle relative to thehandle 415. It will be appreciated that in an embodiment, the angle 425may be selected from a range of between about 30 degrees to about 60degrees. In an embodiment, the angle may be selected from a range ofabout 40 degrees to about 50 degrees. In use, a user may grasp thehandle 415 to steady the machine during use.

The angle of the motor 412 is not vertical or perpendicular to a surfaceon which the machine 400 rests. Thus, a base region of the hopperprovided by the paddle wheel 435 is not horizontal. Rather the paddlewheel 435 provides a base that is tilted at an angle. The angle of thebase may improve performance during the conditioning or ice anddispending of conditioned ice. For example, the paddle wheel 435 istilted toward a location of the blade 430. The tilt toward the blade 430may improve conditioning of ice and may also improve exiting of theconditioned ice through the blade 430. The tilt may also improve howforces or vibrations resulting from conditioning ice are absorbed. Forexample, with the non-horizontal angle of the base, at least some of thevibration or forces are in a vertical direction. These verticalvibrations or forces may be more advantageously absorbed by a surfacevia a base or rubber feet than if all more of the forces or vibrationswere in a horizontal direction. The vertical portion of vibrations orforces may be less likely to be absorbed a user, leading to increasedcomfort for a user and may also lead to longer operation life of themotor 412 and/or machine 400. Thus, the angle of the motor, paddle wheel325, and/or lower region of a hopper may improve performance, machinelongevity, and user comfort.

FIG. 5 illustrates an embodiment of a blade 500 configured forconditioning ice as it is dispensed to a user. Those in the art willknow that when processing ice, ice buildup on equipment can be aproblem. Illustrated in the figure is an embodiment of a blade 500 thatresists ice buildup while providing conditioned ice suitable forconfectionary use. As illustrated, a blade 500 may be an arched orarcuate planar sheet to match a curvature of a wall or housing and maycomprise a plurality of teeth 505. The teeth 505 may be configured asslots or slits in the blade 500 that allow conditioned ice to form on afirst side of the blade and pass through the blade 500 to a second side.In an embodiment, the teeth 505 may be uniform and placed regularlyabout the blade 500. It will be appreciated that in an embodiment theblade 500 may comprise a plurality of offset teeth 505 relative to eachother. For example, a tooth or slot may be vertically offset from aneighboring tooth or slot. The plurality of teeth 505 may be offset inan alternating pattern. Additionally, the teeth 505 may be situated onthe blade in a pattern as is illustrated in the figure. As can be seenin the figure, the teeth 505 alternate between an up position and downposition relative to a center line 555, which is shown as a dashed linein the figure. The offset may reduce icing on the teeth 505 of the blade500. It will be appreciated that any pattern may be employed, forexample, three teeth in a row may be placed in a down position relativeto the centerline 555, while next three teeth are placed in an upposition relative to the centerline 555. The pattern may repeat as manytimes as desired. It will be appreciated that any number of teeth may beplaced in an up position and any number of teeth may be placed in a downposition with respect to the centerline 555 without departing from thescope of the disclosure. Teeth may also be formed with circular holes(similar to those of a cheese grater) or any other hole or slot shape.For example, the teeth may include a square, rectangular, triangular,oblong circular, or other shaped hole. In one embodiment, the holes mayhave a bent or raised edge that protrudes at least slightly above asurface of the planar portion to present an edge for cutting orconditioning the ice. Although the blade 500 is shown having a curvedplanar shape, the blade 500 may be shaped or bent or flattened in otherconfigurations. For example, the blade 500 may include a substantiallyflat planar shape with little or no curvature.

FIG. 6 illustrates an embodiment of a kit 600 comprising a frozenconfection making system that comprises an ice conditioning machine 610and a carrying case 615. The case 615 may comprise a carrying handle616. Additionally, a kit 600 may comprise cups 620 and/or toppingcontainers 625, which may be used to dispense flavors for theconditioned ice, for serving the conditioned ice and creating the frozenconfections. Additionally, a kit 600 may comprise additional items suchas a power cord, battery and backup battery. An embodiment of a kit mayinclude a tool 630 that is specially configured for maintaining the iceconditioning machine 610.

FIG. 7 illustrates a close up expanded view of a lower wall 702 andblade 704 of an ice conditioning machine. The blade 704 may include ablade similar to the blade 500 illustrated in FIG. 5. The lower wall 702may surround a lower portion of an interior of a hopper. The lower wall702 may include clear plastic so that a state of ice and/or the blade704 within the hopper can be seen. In one embodiment, the lower wall 702is integrally formed with a spout 706 where conditioned ice may bedispensed. An opening 708 in the wall 702 is positioned at the spout706. A paddle wheel 710 may be inserted and positioned at a bottom of orbelow the lower wall 702. The paddle wheel 710 may be secured to a driveaxle or motor using a fastener 712. The wall 702 includes a recessed oran indented region bounded by grooves 714. The recessed or indentedregion may have a size matching the blade 704 so that the blade can bereceived into the recessed or indented region. Once positioned, aninterior surface of the blade 704 (a surface that faces inward) may befurther from an axis of the lower wall 702 than an interior surface ofthe lower wall 702 to limit ice from impacting an edge of the blade 704.

The blade 704 is positioned in-line with the lower wall 702 and may havea curvature matching the lower wall 702. When assembled, the blade 704covers the opening 708 in the wall so that ice may only exit the hopperor lower wall 702 through the blade 704. Thus, only conditioned ice mayexit through the spout while remaining ice to-be-conditioned remains inthe hopper.

The lower wall 702 also includes attachment features 716 for securingthe wall to or within a housing. In one embodiment, the blade 704 isreplaceable. In one embodiment, one or more fasteners securing theattachment features 716 may be released to allow a housing or otherportion of a machine to be pulled back and/or up to expose a top regionof the blade. The blade 704 may then be slid upward for removal and anew blade may be slid downward into the recessed or indented portion. Inone embodiment, once positioned, a lower portion of the blade 704 ispositioned in a slot in a housing below the blade and an upper portionof the blade is positioned between the lower wall 702 or spout 706 onthe outside and a portion of a hopper or housing on an upper side. Slitsor slots in the blade 704 may remain exposed so that ice can come incontact with the blade 704 to condition the ice.

The spout 706 may be shaped to impart a desired dome or rounded top to ashaved ice product or snow cone. For example, the spout 706 includes arounded spout with a substantially circular diameter that will form atop shape for conditioned ice as a cup or container is filled. The shapeof the spout 706 may be configured to provide a desired shape and thuscreating a shaved ice product may require little or no shaping aftermoving a container or cup away from the spout 706.

FIGS. 8 and 9 illustrate another embodiment of a machine 800 forconditioning ice. The machine 800 includes a base 805 for supporting themachine on a surface the machine 800 includes a handle 810 with groovesfor providing portability and grip on the machine 800. The machine 800includes a hopper 802 and lid 815 for selectively covering an interiorof the hopper 802. In one embodiment, the lid 815 rests in an at leastpartially open state, as illustrated in FIG. 8. For example, a biasmechanism (such as in a rocker switch) may provide an upper force on aplunger 845 to bias the lid 815 from a closed position.

In order to use the machine 800, a downward force on the lid 815 maydrive the plunger 845 into the rocker switch. When the plunger 845 hascompressed the bias far enough, the switch may activate a motor to beginto spin paddles in the hopper 820 to condition ice. In one embodiment,the switch may activate when a lower lip 850 of the lid 815 issubstantially a same vertical height as an upper lip 855 of the hopper820. In one embodiment, the switch may activate when a vertical distancebetween the lower lip 850 and the upper lip 855 is less than the widthof a finger of a child (about ¼ of an inch or less). The bias and theactivation of the switch may reduce any chance of injury or harm to auser. For example, a user's hands cannot be in the hopper when the motoris turning or otherwise operational.

The machine 800 does not include a latch for holding the lid in or neara closed position. Thus, a constant downward pressure may be required tocondition ice. If pressure is removed, the lid 815 may return to apartially open position, the switch may be opened, and the motor isturned off. Thus, the machine 800 may require that a user's hand bepositioned on the lid in order to condition ice, leading to increasedsafety and decreased chances of movement of the machine 800.

The machine 800 includes a lower wall 835 at a lower region of thehopper 820. In one embodiment, the lower wall 835 and the lid 815include a transparent plastic or glass to allow viewing of the conditionof ice in the hopper 820.

The machine 800 includes a spout 830 with a shaped upper portion 840.The spout 830 has a tapered sidewall sized to accommodate a cup 860, orcontainer of other size, to receive conditioned ice. For example, thetaper may allow a plurality of different cup sizes to be used with themachine 800. The shaped top portion 840 may include an upward bulge onthe spout 830 to allow for a symmetrical dome or rounded top to beimparted to a shaved ice product. The spout 830 include a lower surface865, which guides conditioned ice into the cup 860 and also imparts ashape to a top of the conditioned ice in the cup 860. Thus, a user maysimultaneously receive conditioned ice into the cup 860 and shape theconditioned ice in the cup.

The frozen confection machines as disclosed herein may be used for anyice conditioning purposes. For example, ice may be condition forflavored or unflavored consumption as part of a drink, smoothie, snowcone, slushy, or any other type of drink, recipe, or consumablematerial. The frozen confection machines may also be used as portable orhand operated snow making or ice conditioning for non-consumablepurposes such as for decorations, medical purposes, or the like. Forexample, ice may be conditioned to create snow or shaved ice forplacement in a bag for application to a part of the body to reduceswelling. As another example, ice may be conditioned for snow or icedecorations or the like. The portable and convenient operation, with orwithout a handle, provided by embodiments of the ice conditioningmachines presented herein may allow for conditioning of small to largeamounts of ice for any purpose or in any location.
